I asked before, what are the pixel dimensions, how can you know?

A the initWithData implementations for such as you wish that I have come across need a rect of some type?

I need some help converting a NSString which represents an Image file sent from an iOS device.

The image is the signature for a credit card transaction.

I am receiving all of the data as a CFString on the Mac side.

How can I convert it to an image that I can use in FB?

This is how the data is formatted when sent with other data about the transaction.

  NSData *sigData = UIImageJPEGRepresentation(delegate.signature, 1.0);

NSString *sigDataString = [NSString stringWithFormat:@"%@", sigData];

myString = [myString stringByAppendingString:@" Signature :"];

myString = [myString stringByAppendingString:sigDataString];

myString = [myString stringByAppendingString:lineFeed];



NSLog(@"%@", myString);



NSString *cardDataSend = [NSString stringWithFormat:@"%@rn", myString];

NSData *cardData = [cardDataSend dataUsingEncoding:NSUTF8StringEncoding];



[asyncSocket writeData:cardData withTimeout:-1 tag:0]; //write data to server

thanks

Steve
